Endometrial NK Cells Test – Uterine Immune Function & Fertility Assessment

The Endometrial NK Cells Test is a specialised fertility and immunology test used to assess Natural Killer (NK) cells within the uterine lining (endometrium). This private fertility test helps evaluate immune factors that may affect embryo implantation, IVF success, and recurrent miscarriage.

At Vitalync Diagnosis, we provide advanced reproductive immune testing near you, supporting patients with detailed insights into uterine health.

What Are Endometrial NK Cells?

Endometrial NK (uNK) cells are a specific type of immune cell found in the uterus. Unlike circulating NK cells in the blood, these cells:

Play a role in implantation and early pregnancy development

Help regulate the interaction between the embryo and uterine lining

Support blood vessel formation in early pregnancy

Abnormal levels or activity of uNK cells may be associated with implantation failure or pregnancy complications.

What Does the Endometrial NK Cell Test Measure?

This uterine immune test evaluates:

NK cell concentration within the endometrium

Distribution and density of uNK cells

Immune balance within the uterine environment

Results help identify whether immune factors could be impacting fertility or pregnancy outcomes.

Why This Test Is Important

The endometrial NK cells test is commonly used in:

Recurrent miscarriage investigations

Repeated IVF implantation failure

Unexplained infertility

Advanced fertility assessments

Understanding uterine immune activity allows clinicians to tailor fertility treatment plans and supportive therapies.

When Is Endometrial NK Testing Recommended?

You may consider this private fertility test near you if you have:

Multiple failed IVF cycles

Recurrent pregnancy loss

Difficulty conceiving with no clear cause

Suspected immune-related fertility issues
